1995 XJ Died And Wont stay Runnin

So i was driving my 1995 XJ in the quite crappy weather yesterday down the highway 55 going slow because of the bad weather. Then i noticed this gut wrenching smell what seems like it was coming from my engine bay? i smelled it worse when the heat was on after i smell that Im driving along at 55 and the thing just straight up dies hit the key nothin wouldent stay runnin. So with my better judgement i sadly saw my jeep getting towed for the first time. I got it home and tryed to start it. It will fire and seem like it wants to run but it shuts back down every time it gets up to about a grand almost like its not getting gas? So i hit the key again and put it to the floor revved up real high then it shut down? Now i was thinkin ya know mabey a fuel pump?? BUT this is where im confused i cant hear the fuel pump kick on and when i turn my accesories on, my radio,windshield wipers everything except my domelight WONT work the tac works i know that from when i put it to the floor. So im thinkin like did i fry the computer or what? please if anyone has any knowledge of How mabey why this happened and how i could fix it i would much appriciate it. I hate lookin outside and seeing a busted jeep.

It definitely sounds like an electrical issue. I'm not sure about the smell though can you describe it better?

You may indeed have fried your PCM (although i've never really heard of this happening). Take a look under the hood for anything that looks melted - primarily the power distribution center on the passenger side, and the PCM attached to the driver's side fender.

Another guess would be a burnt up lead to/from the battery/alternator maybe? never know when something will wear the insulation off and ground something out.. and that smell is horrible.

Good advice above.

The smell and the fact that your Jeep died is most likely not coincidental.

Find what burned up and you likely have the root cause of why the vehicle won't run.
